The only thing more frightening than a flash mob of kids is... a mob of children wearing clown suits. Argh!! The annual St. Ann's School Puppet Parade made its way down Montague Street in Brooklyn Heights yesterday. As I'm trying to make a hasty getaway, I saw another clown: Bjork (ha, ha, mercy, that's funny), who lives in the nabe. She looked fab-u, with jet black hair and fashionista blue pumps, though she declined to let me take a pic with her. Sigh.
